Detailed Product Description

IEC 60320-1 Constant Temperature Humidity Climatic Test Chamber Environmental Chamber

Product Overview:

This temperature and humidity chamber is required by IEC60335-1 clause 15, etc.

This test chamber is used for cold, heat, humidity and dryness testing of raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. The purpose is to confirm the products reliability of storage and transportation under high and low temperature alternating heat and humidity.

It conforms to standards:

IEC60320-1:2021 “Appliances couplers for household and and similar general purposes- Part1: General requirements” clause 14

IEC60068-2-1:2007 “Environmental Testing-Part 2-1: Tests-Test A: Cold, IDT”

IEC60068-2-2:2007 “Environmental Testing-Part 2-1: Tests- Test B-Dry heat, IDT”

IEC60068-2-78:2012 “Environmental Testing-Part 2-78: Tests-Test Cab: Damp heat, steady state, IDT”

IEC60068-2-30:2005 “Environmental Testing-Part 2-30: Tests-Test Db: Damp heat, cyclic (12h+12h cycle), IDT”

Structure:

This machine adopts a closed chamber structure with the following features:

A. It has an extremely wide temperature and humidity control range to meet the various needs of users.

B. It adopts a unique balanced temperature adjustment and humidity control mode to adjust the ideal temperature and humidity environment. The heating and humidification capability are stable and balanced, and the temperature and humidity control are high-precision and high-stability.

C. Automatic selection of refrigeration circuit: The automatic control device has the ability of automatically starting the running refrigeration circuit according to the set value of temperature, can start the cooling directly under the high temperature state.

The refrigeration adopts the air-cooled condensing unit with fully enclosed compressor (imported).

D. The door is equipped with an observation window, which is convenient for observing the test state of the test sample.

Temperature and Humidity Range Scheme
Main System Composition
Chamber Body	The inner chamber is made of SUS304# stainless steel plates, rounded shape, smooth and easy for clean
	The outer box is made of 304# stainless steel plate, rounded shape, smooth and easy for clean
	Insulation material: polyurethane foam
	Observation window: double-layer explosion-proof tempered glass
	Shelf: Made of 304 stainless steel, detachable shelf
Heating System	Heating method: electric heating
	Adopting the latest new ceramic heating frame, the ceramic material is resistant to high temperature and with good insulation, will not cause leakage short circuit phenomenon. The middle is connected with German imported heating wire, the wire diameter is thick, high temperature resistance and dry burning resistance. The quartz glass tube is inserted in the middle of the heating wire, to prevent the short circuit fault due to heating wire contacting metal chamber.
	Thermal cycling: forced circulation air duct to ensure the heat transfer of the heater, to prevent local temperature is too high and to ensure the required temperature in the working chamber.
Humidification System	Humidifying method: adopting external humidifying structure, transmitted through the air duct. Advantages are stable speed, small influence on the temperature of the inner box, stable temperature rise, and ideal humidification effect.
	Humidifying tube: U-shape design plus over-temperature probe hole, heating wire and heating system using the same imported brand materials, with anti-dry burning function, to ensure that the humidifying tube has a long service life and is durable.
	HUMIDIFICATION AND REPLENISHMENT: There is a drawer type water filler box. The water level can be visually checked by the level display scale on the circulating water tank. The water level is automatically controlled. Equipped with a water shortage alarm.
Cooling System	Refrigeration method: air-cooled cooling using compressor-heat exchanger
	Compressor: Tecumseh, French brand
	Cold Air Circulation: The forced circulation air duct ensures smooth return and supply air to ensure an even temperature in the working chamber.
Control System	Touch screen: TIME880, SAMWONTECH
	Temperature control: PID self-tuning, using Class A PT100 platinum resistance sensor
	Functions: Fixed value test and programme test Fixed Value Test: When the test environment requires only a single temperature and humidity, select this mode to set the desired temperature, humidity and run time. Programme Test: When the test environment requires multiple temperatures and humidities, select this mode to set the temperature, humidity and run time for each programme. The operator can set the sequence in which the programmes will run, up to a maximum of 100 programmes.
Data Storage	Through the temperature and humidity curve interface, data changes and processes can be recorded; through the standard R232 interface or USB stick communication interface, data can be downloaded.
Safety Protection	Power failure memory function, phase sequence protection, leakage protection, over-temperature protection, compressor overload protection, water shortage alarm, abnormal protection.
